Updates
Note (5/31/2016) - Want a crosshair at the center coordinates of the map? A number of
people have asked, so that option has been added!

Note (6/26/2013) - Map sizes are now larger, and an extra-large (1280x1280)
option has been added as well.

Note (8/18/2010) - The transition to the new TopoQuest server is now
complete. Aside from a glitch that affected the TopoZone alternative
map.asp script much of Monday (8/17/2010) afternoon and evening, all went
pretty smoothly. Response time of the TopoQuest website overall should
be much snappier, and addition of more 1m satellite / aerial imagery is back
underway!

Note (8/2/2010) - Full USGS 1:100K and 1:250K topographic map coverage of the
continental US is now completed and online. Plus, I have the
new TopoQuest server under construction with a 9TB RAID6 disk array to
continue adding satellite/aerial photo coverage. Yay!

Note (7/21/2009) - Locations of places of interest (from the USGS placenames database) within the map area you are viewing
are now listed below the map when viewing at 64m/pixel or below. You can click the name of the place to go to its description page, or click the
coordinates to recenter your map view on that place.

Note (6/1/2009) - We've started adding 1m/pixel aerial and satellite imagery, starting with Oregon and slowly branching out from
there. Please be patient, it takes a very long time to download and process all this imagery, as well as huge amounts
of disk space!

Note (3/07/2009) - We've started adding 1:100K and 1:250K scale USGS topographic maps, starting with southern Oregon and
moving out from there. Coverage will be a bit sparse at first while we crank up automated processing of map tiles
at these topographic map scales. To view 1:100K and 1:250K scale topos, you'll need to manually select them from
the sidebar (the Choose Automatically selection will not select these map scales until we have more coverage).
You can use the coverage map types to see what areas we've already processed and have online. Also note that satellite
photo coverage isn't meant to be particularly useful at this point, it's just (very) experimental.

Note (7/31/2008) - We've started adding 1:50K scale topographic maps of Canada, starting with British Columbia. The
Canadian topographic map coverage is still a bit experimental, and integration into the map viewer still needs a little
work. The map viewer will not yet automatically select the 1:50K scale topographic maps, so if you're trying to view
maps in Canada, you may need to manually switch to the 1:50K Topo Maps selection in the Map Contents section
of the sidebar.

Note (4/15/2008) - With the demise of non-subscription access to TopoZone (now merged
with Trails.com, a subscription service), we're scrambling to process all topographic
maps for the US and make them available as quickly as possible. We now have four
Linux PC's crunching map data 24/7 to produce and index map data continuously. We
should be adding approximately fifteen 1 degree x 1 degree blocks of map data (approximately 1000 individual 7.5 minute 1:24000 topo
maps) per day.
We're starting with southern Oregon (because that's
where we live!) and northern California and branching out from there.

TopoZone URL Replacement
Do you have a Topozone map URL that you want to convert to the TopoQuest equivalent? Simply replace topozone.com with
topoquest.com in the URL, and you'll get the equivalent map as what Topozone used to produce! We have more details on
using TopoQuest as a Topozone alternative on our Topozone Replacement page.
